Abstract
The relationship between macroscopic mechanical and thermal properties and ramp rate during cure of epoxy-amine systems consisting of the epoxide resin digylcidyl ether of bisphenol F (DGEBF, provided Hexion specialty chemicals) and 4,4-diaminodiphenyl sulfone (4,4-DDS, provided by Atul Sulpho) were probed using Dynamic Mechanical Analysis (DMA), Positron Annihilation Lifetime Spectroscopy (PALS), and compression testing. These systems were cured in a programmable oven; the samples were heated from 35°C to 180°C at ramp rates of 0.5, 1.0, 1.5, 2.0, 2.5, 5.0, 10, and 15°C/min. Even as the ramp rates during the cure of these materials was changed, there was very little in properties such as crosslink density, glass transition temperature (Tg), free hole volume, or modulus in the samples.
